How To: Convert points in XYZ file format to raster
Instructions provided describe how to convert points in XYZ format to raster.
3D points in XYZ file format can be first converted to multipoints, and then interpolated to a raster.
Run the Point File Information tool to get the average point spacing, which is the required input to the ASCII 3D to Feature Class tool. Note the value Pt_Spacing in the attribute table of the output feature class.
In ArcToolbax, expand the 3D Analyst Tools node, expand the Conversion node, expand From File, and select the Point File Information tool.
Open the ASCII 3D to Feature Class tool (3D Analyst Tools > Conversion > From File). Select XYZ as Input File Format and MULTIPOINT as Output Feature Class Type. Input Average Point Spacing with the value from Step 1.
Use the interpolation tool (3D Analyst Tools > Raster Interpolation) to interpolate multipoints to a raster.
